Abstract
An assembly that can be used in conjunction with a resin moulding apparatus includes means defining a chamber containing a pressure sensor, and an entry passage leading upwardly into the chamber. The arrangement is such that, when the assembly is mounted in an upper section of a mould and a moulding operation is being carried out, the resin enters the entry passage so that the level of resin in the entry passage increases producing an increase in the pressure within the chamber, and the configuration of the entry passage is such that the cross-sectional area thereof reduces with height.
Claims8
A measurement system comprising a chamber containing a pressure sensor, and an entry passage leading upwardly into the chamber, the arrangement being such that, as the level of a liquid in the entry passage increases, the pressure within the chamber increases, and the configuration of the entry passage being such that the cross-sectional area thereof reduces with height.
An assembly for use in conjunction with a resin moulding apparatus, the assembly comprising means defining a chamber containing a pressure sensor, and an entry passage leading upwardly into the chamber, the arrangement being such that, when the assembly is mounted in an upper section of a mould and a moulding operation is being carried out, the resin enters the entry passage so that the level of resin in the entry passage increases producing an increase in the pressure within the chamber, and the configuration of the entry passage being such that the cross-sectional area thereof reduces with height.
A resin moulding procedure that includes the use of a resin moulding apparatus including a mould having an upper section and an assembly comprising means defining a chamber containing a pressure sensor, and an entry passage leading upwardly into the chamber, the arrangement being such that, when the assembly is mounted in the upper section of the mould and a moulding operation is being carried out, the resin enters the entry passage so that the level of resin in the entry passage increases producing an increase in the pressure within the chamber, and the configuration of the entry passage being such that the cross-sectional area thereof reduces with height.
